Unhealthy digestive tract can be attributed to a gut microflora that has an overgrowth of bad bacteria and a dwindling good bacteria colony. When there is an abundance of bad bacteria, they will metabolize food and produce a lot of toxins.

Initially, the movement of food through the intestinal tract will slow down because the muscle contractions that cause the food movement are getting weaker, resulting in stomach-ache, bloatedness, and many other accumulated bowel symptoms. These accumulated bowels will further produce even more toxins.

These toxins will be absorbed by the mucous membrane of the intestinal tract, and reach the liver via the hepatic portal vein. When your liver is healthy, it can metabolize these toxins. But when your liver is overworked and fails to metabolize all the toxins, these harmful substances will seep into the bloodstream together with the other nutrients. Within one minute, toxins would have travelled throughout the body one cycle, thus giving rise to all kinds of pre-disease symptoms beyond just stomach disorder.

In the beginning, you would experience mental problems such as emotional instability, irritability, nervousness, loss of interest in work, attention deficiency, negative thinking and so on.

When toxin accumulates to a point that it affects the Peripheral Nervous System (PNS), you would start to experience back pain, Lumbago (lower back pain), headaches and other symptoms.

When it affects the Central Nervous System (CNS), you would begin to feel fullness in head, sleeping disorders, and fatigue even when you wake up.

When toxin accumulates to a certain extent, it will affect the Autonomic Nervous System (ANS). In serious condition, it can cause severe vasospasm, causing dizziness, shortness of breath, chest pain, cold hands and feet, night sweats and other symptoms.

Next, you will finally experience rapid skin aging, resulting in acne, rashes, wrinkles, and so on.

Therefore, it is important to maintain a healthy microflora balance; the ideal being at least 80% of good bacteria to 20% of bad bacteria. Many people are taking probiotic supplement such as yogurt to supplement their bacteria colony. But these bacteria are from external sources. You are unlikely to “eat” live microorganism on a long term basis. To foster a long term solution, the better way would be to take prebiotic, that is by consuming nutrients that can nourish and stimulate the growth of the natural occurring bacteria colony within your body.

Hepatic portal vein is a blood vessel that conducts blood from the gastrointestinal tract and spleen to the liver.

Peripheral nervous system (PNS) is the part of the nervous system consisting of the nerves and ganglia outside of the brain and spinal cord. The main function of the PNS is to connect the central nervous system (CNS) to the limbs and organs, essentially serving as a communication relay going back and forth between the brain and the extremities.

Autonomic nervous system (ANS or visceral nervous system or involuntary nervous system) is the part of the peripheral nervous system that acts as a control system, functioning largely below the level of consciousness, and controls visceral functions. The ANS affects heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), and sexual arousal. Most autonomous functions are involuntary but a number of ANS actions can work alongside some degree of conscious control. Everyday examples include breathing, swallowing, and sexual arousal, and in some cases functions such as heart rate.

Night sweats is the occurrence of excessive sweating during sleep. The sufferer may or may not also suffer from excessive perspiration while awake. One of the most common causes of night sweats in women over 40 is the hormonal changes related to menopause.
